BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a dust brush, and more particularly, toa dust brush in which an advertising piece printed with variousadvertising wordings, patterns, logos, or the like on one side of a bodyof the dust brush is detachable to the dust brush, and a ring formed ina rear end of the body is rotatable and detachable.

2. Description of the Prior Art

Generally, dust is flowed into a room, such as a home, and is depositedon various types of furniture. Thus, this dust is flowed into a humanbody when a person breathes to injure his health. Therefore, this dustmust be periodically removed.

In addition, dust is deposited on a vehicle. Thus, when the dust islargely deposited on it, it is not good in appearance, as well as whenthe dust is deposited on it, it obstructs a driver's field of view todisturb a driver's safe drive.

For this reason, most of vehicles are essentially provided with a dustbrush.

FIG. 1 shows a dust brush, particularly, a dust brush used for avehicle. This dust brush 10 is configured in the form that a brushingportion (its reference numeral is not given) made in a form which acloth, a piece of cloth, or the like is twisted is detachably connectedand fixed to a body 12 with a fixed length, as shown in the figure.

In addition, the dust brush 10 is made to have a structure in which alatch 14 is integrally formed with the end of the body 12 in order tohang it on a hook in a sidewall of the vehicle.

Therefore, when user intends to brush the dust deposited on the vehicle,and the like, the user suffices to grip the body 12 and brush the outersurface of a vehicle body and an outer surface of a glass with thebrushing portion of the dust brush. After using, the dust brush is putinto the trunk of the vehicle or the latch 14 of the dust brush ishanged on the hook in the sidewall of the vehicle and then kept.

However, the dust brush, and the like as above-mentioned is mainly usedas a gift expressing the gratitude because its manufacturing cost isrelatively cheap.

That is to say, there are many cases that when a vehicle seller presentsthe dust brush to a buyer as a gift, print a he/her own name, atelephone number or a name of business office on one side of the body ofthe dust brush and then present it to the buyer for the sake ofadvertisement, and that also in the other business place, for the sakeof above purpose, print various advertising wordings, patterns or logos,and the like on one side of the body and then present it to the buyerfor the sake of advertisement.

However, the dust brush as above-mentioned is that most of a body ismade from a synthetic resin. Therefore, its manufacture is realized byan injection molding. Thus, when one intends to print the advertisingwordings, patterns or logos, a mold accordingly should have been made.

As well known, since the mold costs a great deal in its manufacture, itis economically inefficient to individually make the mold in which theexpensive is heavy in order to manufacture a temporary and limitedproduct. Accordingly, there is a problem that the seller or the businessplace that intends to manufacture the dust brush for advertisement has alarge burden in view of cost.

In addition, a latch formed in the end of the body of the dust brushalso was integrally formed by the injection molding upon manufacturing.Therefore, when hanging the latch on the sidewall of the vehicle, thelatch is hooked only in the one direction.

SUMMARY OF THE INVENTION

The present invention is conceived to solve the aforementioned problems,and it is an object of the present invention to provide a dust brushthat minimizes the manufacture cost by manufacturing an advertisingpiece printed with various advertising wordings, patterns or logos, andthe like on one side of a body of the dust brush, and the body to whichthe advertising piece is detachable, as separate objects, respectively,and after mass producing the body, mounting the advertising piece thusmanufactured to the body, as required.

In addition, it is a further object of the present invention to providea dust brush that its hanging becomes easy by constructing such that thelatch formed in the rear end of the body can be rotated.

According to the present invention for achieving the object, there isprovided a dust brush comprising a body integrally formed with a handle,a brushing portion which is made of a cloth or a piece of cloth and isdetachably provided with the body, and a latch formed in a rear end ofthe body, comprising: a rest recess having an engaging hole and formedon one side of the body; a separate advertising piece in which engagingprotrusions corresponding to the engaging hole are formed to bedetachable to the rest recess of the body, and on the top surface ofwhich various advertising wordings, patterns or logos, and the like areengraved; and a latch which is mounted in the rear end of the body to befreely rotatable at 360°.

In addition, there is provided a dust brush further comprising anengaging hole formed in a rear end of the body, and gripping piecesformed on an one side of the latch and having a little larger diameterthan that of the engaging hole and can be pursed by an elasticity,wherein the gripping piece of the latch is forced into the engaging holeof the body and is rotatably mounted therein.

Meanwhile, there is provided a dust brush further comprising an engaginghole formed on one surface of the rear end of the body, a guide pieceformed with an engaging protrusion corresponding to the engaging hole tobe inserted closely to a rear end inner surface of the body, and aseparate detachable portion which the latch is freely, rotatably mountedto its engaging hole, wherein the latch is constructed to be detachablymounted to the body.

In addition, there is provided a dust brush, further comprising a palmshaped gripping portion formed on a surface of the body so as to easilygrip the body when a user grips the body using a user's own hand.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Hereinafter, preferred embodiments of the present invention will bedescribed in detail with reference to the accompanying drawings.

In describing the present invention, parts identical to those of theprior art will bear identical same reference numerals thereto and theoverlapped description thereof will be omitted.

FIG. 2 is a perspective view showing a dust brush according to thepresent invention, and FIG. 3 is a sectional view of the primary partsof FIG. 2.

As shown, the dust brush 10 of the present invention is provided with arest recess 24 having engaging holes 26 on one side of its body 12.

That is to say, the body 12 is manufactured by an injection molding in astate in which the rest recess 24 as above is formed on its one side.

In addition, an advertising piece 20 which can be attached and detachedto and from the rest recess 24 is manufactured separately, and thisadvertising piece 20 is formed with engaging protrudes 22 for insertingand fixing to the engaging holes 26 of the rest recess 24, and variousadvertising wordings, patterns or logos are engraved on the top surfaceof the advertising piece, as requirements of an orderer.

Accordingly, a manufacturer massively produces the body 12 formed withthe rest recess 24 as described above and then engraves the variousadvertising wordings, the patterns or the logos only on the advertisingpiece 20 according to the number required by the orderer. Therefore, itsuffices to only mount the advertising piece 20 thus manufactured to thebody 12 and give it to the user.

In addition, a latch 30 is rotatably mounted in the rear end of the body12.

That is, as shown in FIG. 3, an engaging hole with a fixed size (itsreference numeral is not given) is formed in the rear end of the body12, and a latch 30 is inserted and fixed into and to this engaging hole.

That is to say, the latch 30 is formed with gripping pieces 34 having anelasticity to be pursed by a predetermined amount in the other surfaceof a ring 32. Here, since a size of the gripping pieces 34 is formed tobe larger than a diameter of the engaging hole of the body 12, the usersuffices to force the gripping pieces 34 of the latch 30 into theengaging hole of the body 12.

If so do, the gripping pieces 34 of the latch 30 are pursed under theelasticity force and then passed through the engaging hole. Thereafter,if these gripping pieces 34 are entirely entered into the engaging hole,they are widen by their own elasticity and then engaged with an innertongue portion of the engaging hole. Consequently, the gripping piecesare fixed not to be detached there and also the latch 30 is freelyrotatable at 360°

Therefore, in case of hanging the dust brush 20 on the hook of thesidewall using the ring 32 of the latch 30, one can hang the dust brushin a desired state by freely rotating the latch 30.

Meanwhile, FIG. 4 is a perspective view showing a dust brush accordingto another embodiment of the present invention, and FIG. 5 is asectional view of the primary parts of FIG. 4, wherein it also ispossible to detachably construct the latch 30, as shown the figure.

That is, as in above-mentioned embodiment, if the latch 30 is forcedinto the rear end of the body 12, it is not easy to detach it.Therefore, there may be a problem that the functionality of the latch 30is entirely lost, if the ring 32 of the latch 30 is destructed.

Accordingly, the present embodiment forms a detachable device 40 whichis inserted into the rear end of the body 12, as a separate object, andthus it suffices to force the gripping piece 34 of the latch 30 into theengaging hole (its reference numeral is not given) of the detachabledevice 40 as in the above embodiment, and to detach the detachabledevice to the rear end of the body 12.

Then, the detachable device 40 is provided with guide pieces 42 to beinserted while abutting on an inner surface of the rear end of the body12.

That is, an engaging hole 12a is formed on one side of a rear end of thebody 12, and an engaging protrusion 44 corresponding to the engaginghole 12 a of the body 12 is formed on one side of the guide piece 42 ofthe detachable device 40. Therefore, it is possible to detachablydispose the detachable device relative to the rear end of the body 12.

Accordingly, when a ring 32 of the latch 30 is broken so that it cannotbe used, it suffices to separately purchase only the detachable device40 and replace it.

In addition, a surface of the body 12 is formed with a palm shapedgripping portion 46 so that when a user grips it using a user's ownhand, the user's hand is guided by the palm shaped gripping portion.Thereby, the user grips it more easily.

As described above, according to the dust brush of the presentinvention, there is advantage that the orderer or the manufacturer canorder or manufacture the dust brush for advertisement or publicinformation with a low cost, by manufacturing the body formed with therest recess on one side, and separately manufacturing the advertisingpiece which is detachable to the rest recess of the body, and on its topsurface of which various advertising wordings, patterns or logos, andthe like are engraved according to the orderer's order, or bymanufacturing in a state which the advertising piece is mounted to therest recess of the body, as required.

In addition, there is an advantage that since the latch formed in therear end of the body is configured to be freely rotatable, it can easilyhang the dust brush on the hook in the sidewall of the vehicle.

Meanwhile, in case the latch is constructed to be detachable to thebody, it suffices to exchange only this broken portion on breakage ofthe latch. Therefore, there also is an advantage reducing theunnecessary expense.

Though the present invention has described with reference to aboveembodiment, it is be appreciated that modifications may be made withoutdeparting from the spirit of the present invention
